@Amjad Nagori Thank you for reaching out to Microsoft Q&A.
I understand that you want to setup connectivity between Azure Government Virtual Network and Azure Global (Public) Virtual Network. To do that you can setup a site-to-site VPN between the two vnets. The steps are the same except that the Local Network Gateway would point to the other vnet's VPN gateway (instead of an on-prem device). Please give it a try to setup the same and let me know if you need any further assistance. Thank you!
